Steel Dust Recycling is our newest plant in the United States dedicated to the recovery of industrial zinc and lead waste. This plant recycles Electric Arc Furnace (EAF) steel dust using Waelz Kiln technology.
EAF dust generated by steel mills contains zinc. The new SDR plant specializes in the recovery of zinc and other metals from this dust. The main product of SDR is Waelz Oxide, also known as Crude Zinc Oxide (CZO). This product is transformed into zinc oxide, zinc sulfate or metallic zinc through zinc smelting. Our plant also produces Waelz Iron Product (WIP), an iron concentrate..
As of October 1st, 2009, SDR became part of Grupo PROMAX, the group that owns Zinc Nacional, which has more than 30 years of experience in recycling EAF dust.
Zinc Nacional, founded in 1952, is a private company dedicated to the production of zinc compounds and recycled cardboard. The main objective of this acquisition is to allow Zinc Nacional, with the inclusion of SDR, to provide a closer service to the steel industry in the United States, while also providing more zinc units for the production of zinc oxide and zinc sulfate in its facilities in Monterrey, Mexico.
